From c69dbbf3335a21aae74376d7e5db50a486d52439 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Mon, 17 Feb 2014 23:03:08 +0300 Subject: mtd: nuc900_nand: NULL dereference in nuc900_nand_enable() Instead of writing to "nand->reg + REG_FMICSR" we write to "REG_FMICSR" which is NULL and not a valid register.
